Lin Mo widened his eyes; he could now clearly see the appearance of this monster, which turned out to be a giant two-headed evil dog, standing about four meters tall and roughly six meters long. The red eyes on both heads emitted a fierce glow.

If he were outside the Ancient Battlefield Ruins, Lin Mo could easily handle such fierce beasts, but now his mana is suppressed, leaving him only with his body's explosive power.

Double-headed Hellhound, Lin Mo thought of the monsters recorded in the tomes given to him by Qiao, one of the monsters raised by Lucifer, and admittedly, among them was the most formidable nine-headed evil dog.

Lin Mo held his breath, reducing his body's energy to the lowest level, hoping that this evil dog would not discover his presence.

The double-headed hellhound slowly walked out of the passage, its four eyes resembling fiery red lanterns, looking around, then sniffed the air as if it had caught a whiff of human scent.

"Roar!"

The head on the left side of the hellhound suddenly lifted, its two fiery red eyes staring intently at the horizontal pillar above, with two fierce glows in its eyes.

"Damn it, I've been discovered."

Lin Mo's face slightly twitched, pressing down forcefully with his foot, his entire body flipped backward. Simultaneously, the mouth of the left head of the hellhound opened, and a scorching fireball shot out like a cannonball, hitting the spot where Lin Mo had just been standing, shattering the beam into several pieces that crashed to the ground, raising a cloud of dust.

Whoosh, whoosh!

Two black shadows shot through the air as fast as lightning, with a piercing sound.

As Lin Mo landed on the ground, both his feet skidded across the gravel, carving two long dust trails, while his left hand gripped the Willow Leaf Blade, throwing it with full force.

Two Willow Leaf Blades sliced through the air like two black lightning bolts, forming streamlined tails of airflow.

A low growl of anger, the seemingly bulky body dodged quickly to the side, but at such close range, combined with Lin Mo's full-force throw, the speed of the two Willow Leaf Blades struck it in the blink of an eye.

"Clang, clang!"

The sound of two crisp impacts echoed, leaving Lin Mo stunned.

The two Willow Leaf Blades were forged from specially tempered steel, inscribed with runes to greatly enhance their toughness and sharpness, capable of easily piercing ordinary steel plates.

However, the body of the double-headed hellhound was even harder than steel, producing two sparks and deflecting the Willow Leaf Blades, embedding them into the side wall.

"Roar!"

The double-headed hellhound's four eyes locked onto Lin Mo standing not far away, with endless fury in its gaze, releasing a fierce and angry growl.

Damned human!

Lin Mo was startled and scared; not only was this double-headed hellhound's body as hard as iron, but it could also use magical attacks. With his current strength, killing the double-headed hellhound was indeed a daunting task.

But at this moment, Lin Mo couldn't afford to think anymore.

The double-headed hellhound's powerful four paws thudded on the ground, raising clouds of dust as it charged forward as swiftly as a Black Panther hunting in the African jungle, its two mouths opening to reveal serrated, sharp teeth, with traces of transparent liquid, exuding a strong stench.

"Such speed!"

Lin Mo's eyes widened, his body contorting to an extremely bizarre angle, narrowly dodging the charging hellhound, but his shoulder felt like it had been hit by a train, a powerful force threatening to tear his body apart.

"Bang!"

Lin Mo's body skidded across the ground, carving a nearly hundred-meter dust trail in the gravel, stopping only by crashing into a broken stone pillar.

Lin Mo glanced to the side, frowning. Earlier, his left shoulder had been grazed by the hellhound's claw, leaving a red claw mark on the torn fabric, with trickles of fresh blood seeping out.

"Damn it, if not for my enhanced body, this claw would've left a bloody hole in my left shoulder." Lin Mo gritted his silver teeth, his gaze sharp.

The double-headed hellhound did not launch another immediate attack; its four fierce red eyes scrutinizing the human before it, clearly surprised that its titanium alloy-like claws had not shredded this young man.

"Beast."

Lin Mo slowly stood up, grasping a dagger in his right hand, his eyes flashing a sharp gleam. Pushing off with his foot, he lunged diagonally, piercing the air with a sharp whistle.

With the eruption of Blood Demon Vine Emperor's Four Symbols Power, Lin Mo's muscles tensed, his speed and strength taking on a geometric, exaggerated growth. The double-headed hellhound sensed danger; the human's aura before it had magnified many times over. The double-headed hellhound opened its mouths, conjuring two scorching fireballs in its jaws that exuded intense heat from dozens of meters away, capable of melting gold and silver.

"Whoosh, whoosh!"

Two fireballs burst from the hellhound's mouths like cannonballs, trailing scorching fire streams.

At this moment.

The corner of Lin Mo's mouth curled into a strange smile, his body suddenly vanishing from sight, almost brushing past the fireballs by a hair's breadth, his speed accelerating once more, approaching the double-headed hellhound like lightning.

"Die!"

Lin Mo's right hand bulged, veins popping, his tightly gripped black dagger transforming into a black lightning bolt, stabbing fiercely into one of the eyes on the left head.

Immediately, Lin Mo kicked down on the eye and leapt high onto a horizontal beam.

"Huff!"

Lin Mo panted heavily, his chest heaving, as the power of the Four Symbols could only sustain his body for a few minutes, placing a huge burden on his physique.

The double-headed hellhound's entire skin was as hard as steel; Lin Mo could only target vulnerable areas like the eyes, throat, nose, ears, and mouths.

Blood gushed from the left eye of the left head of the double-headed hellhound, emitting a shrill and angry cry, its roar shaking the surroundings with towering anger.

"If I don't finish off this thing quickly, the noise might attract other wild beasts." Lin Mo frowned secretly, his foot stomping down again as his whole body exploded forward like a bolt of lightning.

...

Several minutes later, the double-headed hellhound finally fell. Its four eyes were bleeding, and its head had a fist-sized hole, with dark blood continuously flowing out.

Lin Mo's muscles trembled throughout his body; this was the aftereffect of enduring excessive strain, his strength thoroughly drained. Even a Black Ring Snake could probably take him down.

Lin Mo gathered his resolve and immediately used the dagger to cut open the double-headed hellhound's two heads, extracting two dark red crystals.

"The energy contained in these dark red crystals is dozens of times stronger than energy crystals, equivalent to obtaining dozens of top-grade energy crystals." Lin Mo grinned.

Wonderful events continue tomorrow.
